The invention relates to the field of vehicle control, in particular to a system based on vehicle speed planning and energy management strategy collaborative optimization and an application method. The system comprises an offline optimization subsystem and an online application subsystem, wherein the offline optimization subsystem comprises a scene pre-analysis module and a multi-dimensional dynamic planning algorithm module; the online application subsystem comprises a double-LSTM (Long Short Term Memory) model module and a vehicle-mounted control module; according to the invention, the scene pre-analysis module obtains and analyzes the scene of the urban continuous intersection; then solving a vehicle speed sequence and a fuel cell control sequence with the optimal comprehensive performance through a multi-dimensional dynamic programming algorithm module, and taking the vehicle speed sequence and the fuel cell control sequence as a training data set; the economic vehicle speed and the fuel cell output power are obtained through the double-LSTM model module; and the output power of the power battery is obtained through the vehicle-mounted control module. Therefore, the optimal output power of the fuel cell and the power cell at each moment is determined by considering external interference factors from driving scenes such as traffic lights and front vehicles and economic vehicle speeds.
